Levelthreshold has been increasing in popularity for the last 10 years. In recent years Stormtech has developed a particular expertise in doortrack and threshold drains. In addition to custom work solutions, Stormtech has developed an off the shelf level threshold solution.

The 65TDI consists of a 65mm wide linear stainless steel wedgewire grate, with an integrated concealed channel section which connects all sub sill sections. This threshold drain allows doorsills to be drained while having internal and external floor surfaces with zero stepdown. The system is suitable for all bottom rolling and top rolling door sills and allows internal and external floor surfaces to be equal with zero step down.
